主　　题：HVOF TiB_(2)-Ni Microstructure Abrasive wear Corrosion 

摘      要：TiB_(2)–Ni coatings with different binder phase contents were sprayed on Q235 substrate by a high-velocity oxygen-fuel(HVOF)method using ball-milled *** microstructure,phase compositions,as well as thermal shock behavior,abrasive wear,and corrosion resistance to molten Al-12.07 wt%Si alloy performances of as-sprayed coatings were *** results show that the three TiB_(2)–Ni coatings structure is dense with low porosity,and the main phase compositions of the coatings are TiB_(2) and Ni similar to those of original *** coatings that have superior performance of thermal shock resistance have good bond to the substrate with no change in thick-ness and microstructure of ***,the coat-ings also have good durability in the molten Al-12.07 wt%Si after 60-h immersion *** the mass loss of Q235 steel is five times as much as that of TiB_(2)–50Ni coatings after abrasive wear test.
